01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Secure the connection for every journey
The quiet backbone of any towed load, this harness sits beneath the surface of your vehicle’s rear, ready to transmit light and signal with precision. It is the unseen link that ensures your brake lights respond instantly when you slow down on a winding road.
Designed for trailers, boat hitches and utility carts, this 4-pin 5-wire kit connects side taillights, brakes and turn signals. It suits drivers who value reliable electrical performance over complex diagnostics.
02MATERIALS
Built to withstand the elements
At its heart lies high-quality copper wire, encased in a thickened PVC coating that offers robust protection against daily wear. The outermost layer features a reinforced black nylon net tube, adding structural integrity to the bundle. This layered construction helps resist adverse weather conditions, ensuring the insulation remains intact whether exposed to rain, sun or road debris.
04COMPATIBILITY
Standardized fit for diverse hitches
The connector is designed to match the industry-standard 4-way flat socket, serving as a direct replacement for existing 4-flat connectors. It provides a male plug suitable for marine boat trailers, ATV haulers and general cargo utility trailers. Note that the towing vehicle must be equipped with a corresponding 4-way plug; this specific harness is not intended for motorcycle trailer wiring configurations.
